(Germany single rack cylinder,produced by Hengyu Hydraulic Cylinder Factory）

single rack cylinder are widely used in Germany，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed single rack cylinder for customers from Germany.

Introduction to single rack cylinder:

Under normal circumstances, the single rack cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the single rack cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the single rack cylinder and the end cover, the piston and the piston rod, the piston and the single rack cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the single rack cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

How the cavitation of the single rack cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the single rack cylinder, resulting in corrosive damage to the parts.

single rack cylinder and hydraulic station selection: Select the type and structure of the single rack cylinder according to the operation requirements of the main engine. According to the external load force borne by the single rack cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the single rack cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the single rack cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the single rack cylinder, the diameter of the piston and the piston rod.

single rack cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the single rack cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the single rack cylinder. c. The single rack cylinder seal is extruded, if the O-ring is obviously extruded at the single rack cylinder seal, replace the single rack cylinder seal.

Answers to some questions about single rack cylinder:

Classification and application of cylinders.
Hydraulic cylinder is divided into single acting hydraulic cylinder, double acting cylinder, combined hydraulic cylinder, swing hydraulic cylinder. Single acting cylinder is divided into plunger type hydraulic cylinder, single piston rod hydraulic cylinder, double piston rod hydraulic cylinder, telescopic hydraulic cylinder. Plunger type hydraulic cylinder: the plunger moves only in one direction, and the return stroke is to push the plunger back using its own weight or load. Single piston rod hydraulic cylinder: The piston moves only in one direction, and the return stroke is to push the plunger back using dead weight or load. Double piston rod hydraulic cylinder: both sides of the piston are equipped with piston rods, and pressure oil can only be supplied to one side of the piston. The return stroke usually uses spring force, gravity or external force. Telescopic hydraulic cylinder: It obtains long stroke with short cylinder. The hydraulic oil is pushed out from large to small section by section, and the external force is reduced from small to large.

How to produce good quality hydraulic cylinder?
According to the principle of quality control, it is considered from five aspects: people, machine, material, method and environment. 1, People, refers to the processing and assembly operators. Their skills, professional qualifications, literacy should meet the requirements of production. For example, do your machining workers have the required grade certificate? Do your welders have welding certificate? 2, Machine, refers to your production equipment. Production cylinders have requirements for processing equipment. For example, the piston rod requires chrome grinding. Can your equipment meet the need? 3, Material. The material you use should meet the quality requirements. For example, the sealing ring of PARK and domestic goods is different. Material is also very important. 4. Method refers to the process method. Do your processing and assembly processes meet the requirements? 5, Environment. The environment shall be neat and orderly, clean and hygienic. It is especially important for the hydraulic cylinder production enterprise environment. Can your assembly shop site be clean and dust-free? Quality inspection is also a focus of control. Products should do pressure test, leakage test. The test pressure should reach 1.25 times the design pressure. If you can't maintain pressure, what about quality? You may not be able to do the whole process of cylinder production, you can take the method of OEM. Taking advantage of the strengths of specialized manufacturers, you contract out what you need and then assemble it yourself. But the principle of quality control is the same.
